Zune software The Zune software functions as management software for the device, a full media player application with a library, an interface to the Zune Marketplace, and as a media streaming server. Zune Software is used to sync with all devices with Zune functionality, including the Zune devices, Windows Phone 7, and Microsoft Kin. Zune devices work exclusively with the Zune software and Marketplace. The Zune software organizes the media in its library and allows users to add to the library by ripping from CDs, syncing with a Zune device, and downloading from the Zune Marketplace. The Zune software also allows one to organize song metadata. It can automatically download album art and metadata tag data for content in the library.

On the PC, the Zune software streams files to other PCs, the Xbox 360, and other compatible devices.

Windows Phone 7, Kin, and all previous Zune devices will still use the Zune software, which is still available for download on the Windows Phone website.
